Specification of Letters Patent. Pat (1] (((l Apr. 26. 15)).

Application tiled Februa y 19. 1905); Serial No. 478.762,

To altivhom it may concern:

adapted to receive and support suitable bris- Be it known that l..\1n:'rn C. hsuor. a tles 9 which areot' a length such that they citizen ofthe United States. residing at East will Cleveland, in the county ot'tirvahoga amt State of Ohio, have invented certain new and useful Imu'ovements in 'l vpe (.leancrs, of which the "following is aspecification.

This invention relates generally to type cleaners for typewritiugmachines, and particularly to that class of such devices wherein thetype are adapted to be thoroughly cleaned by a suitable-ln'ush.

More specifically the invention relates to a cleaner for typewriter typewherein a suitable member carryingn brush, normally out of the range ofthe type, is adapted to be moved over the gang of type as they remainat. rest and sweep the dirt from the face thereott'.

Still more specifically the invention relates to suitable guidesarranged upon the typc- Writer frame and sup iorting a suitable carriagehaving a brush which is normally held out of range of the type, but isadapted to be moved back and forth across the face of the gang of typewhen they are idle.

The invention may be further brietly summarizled as consisting in theconstruction and combinations of parts hereinafter set forth in. thefollowing description, drawings and claims.

teterring to the drawings, Figure l is a front elevation of a portion ofthe t'rame of a modern typewriter with my device applied thereto; Fig. 2is a top plan view of the frame with the device in place; and Fig. 3 isa section upon the line 3 3 of Fig. 2.

In carrying out. the invention any preferred l'orm and construction ofparts may be employed so long they possess the necessarycharacteristics, but I have shown one form in the drawings which meetsthe requirements very eli'ectively, and in such embodiment 1 representsthe side frames of the machine supporting the top 'frame 2 which isprovided with suitable guide n'iembers 3 having guiding heads 4.Slidably mounted upon these guiding beads are the side members 5 of thecarriage (S which is in the form of a plate of a shape to conform to thearrangement of the type as they stand in rest position. In this instanceit is semicircular or arcshaped as the type are shown in Fig. 1 and Fig.2 in such arrangement. Secured on the end face of this plate. (3 is aSQlll -ClFCllltlP or are-shaped brush baclt 7 brush the lace ol the typewhen they are moved across the same.

Secured to the plate ('1 and to the back T of the brush is a 'l'rontplate J substantially the form shown in Fig. l and having thereon athumb piece 10 which may be grasped by the operator in using the device.6.

'lhc normal position of the carriage is forwnrd and this is broughtabout by springs 11 each engaging at-onc end a hook I! secured toeach-guiding member 3 near its end and engaging another hook l3 mountedupon a stud 14 forming a part of the iran'ic.

In using the device the operator may devote very little timein cleaningthe type for every now and then thetluuub piece may be grasped and thecarriage ti, carrying thc7 brush. may be shifted back and forth acrossthe face of the type, thus thoroughly cleaning the same. and when not inuse it is out of the range ol' the type in the position shown in Fig. 2,it being held in such position by the springs 11.

The brush is hidden from view by a. snitable guard plate 15 secured tothe machine frame in any suitable manner.

llaving described my I clann:

I In a front-strike typewriter, in combination. a frame having an uppermember provided with an opening therein for the passage oi the typ'c,guiding members one arranged on each side of such opening, a carriageslid-ably mounted in said guiding members and adapted to be shiftedacross the faces of the type as they remain in a state of rest, acleaning device upon said carriage and adapted for engagement with thefaces oi the type, and means whereby said carriage may be shifted tomove the cleaning device across the faces of the gang of type.

2.
